MIXING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 781,728, dated February '7, 1905.

Application filed November 17, 1903. Serial No. 181,505.

Be it known that I, IVILLIAM J. J UDD, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Mixing-lllachines, of which the following is a specification.

Prior to my invention it has been usual in mixingconcrete at one point and conveying it to some remote point to first mix the concrete in a suitable mixer and then dump a batch or a suitable portion thereof into a bucket and transport the bucket to the point where the concrete is to be used by a carrier system, for example, comprising what may be termed a trolley system, adapted to cause the travel of the bucket and involving an arrangement whereby the bucket can be raised and lowered.

Objects of my invention are to provide a simple and more economical arrangement, to save time, to utilize the power heretofore employed for transporting the bucket as a means for causing the mixing up of a batch of concrete, and to provide an efficient and improved arrangement for mixing and delivering the concrete on occasions where, for example, the engine is on the bank of a river or excavation and the concrete is to be delivered and used at a point more or less remote from such bank.

In the accompanying drawings, Figure 1 represents in elevation a concrete-mixing system embodyingthe principles of my invention. Fig. 2 is a section on line u a in Fig. 1 looking in the direction of the arr0ws,so as to show in elevation the carrier and the mixing-receptacle.

The mixing-receptacle A, broadly considered, may be of any suitable type or construction consistent With the purpose for which it is intended. As herein illustrated the mixingreceptacle, as a matter of further improvement, is a cube-box mixer having a door B, which can be opened for the passage of material and closed during the operation of mixing. The mixing-receptacle is provided with a sheave C, arranged in a plane transverse to the axis of rotation and midway of the terminal of such axis, or substantially so.

1) indicates a bail arranged to straddle the mixing-receptacle, which is pivoted or journaled to the ends of said hail, the axis of the pivots or journals thus formed being coincident with the axis about which the mixingreceptacle is arranged to revolve. The mixing-receptacle is suspended by a cable E, which passes about sheave (l of the mixing-receptacle, one portion of such cable passing upwardly to engage a guide-pulley F on the bail l) and thence upwardly to and over a pulley 1 on the lower portion of the carrier (l, thence to a pulley 2- on a suitable support 3, and thence to the engine drum or spool 4. The other portion of said cable E in like manner engages a pulley F on the bail, thence passes through and over a pulley 5 on the carrier (1 and thence passes to some suitable device where it is anchored, the device illustrated for such purpose being a support 6.

The carrier (1" is provided with wheels or pulleys T, which are supported upon and arranged to traverse a cable ll, anchored at both ends, and for purposes of illustration one end of such cable is shown tied to support 3, while its opposite end is shown tied to the support 6. The carrier G is moved back and forth along the cable H by means of a cable I, connected with the carrier and passing over pulleys at opposite remote points and also connected with and operated by the engine-drum 8 or like suitable means.

The mixing-receptacle U can be suitably charged with materials at one end of the system and then caused to travel toward the opposite end of the system and also stopped at any desired point by operating the cable I in a proper direction. During this travel on the part of the carrier (i and the mixing-receptacle the latter will be revolved by reason of its engagement with the cable E, which will necessarily be caused to relatively traverse the sheaves or pulleys 1 and 5 in opposite directionsas, for example, if the carrier G- (shown in Fig. I) is traveling to the left the depending portion 9 of cable E will relatively pay out downwardly from pulley 5, while the 1, the reverse of said action being of course attained when the carrier G is moved in an opposite direction. In this way the mixingreceptacle can be charged at or adjacent to the point where the engine is stationed-for example, on a bank-and the mixing-receptacle can then be caused to travel to a remote point from the excavation, and during such travel it will revolve and mix together the materials so as to form a batch of concrete. When the mixing-receptacle reaches a point over the place where the concrete is to be used, it can be lowered by causing cable E to pay out from the pulley 2 in the same way in which a bucket, as heretofore, has been lowered from a like or similar carrier or trolley system or device. I am enabled, therefore, to use the power heretofore employed for moving a bucket to transport the mixing-receptacle which takes the place of a bucket, and with little additional power to cause the mixing-receptacle to revolve and mix up 'the materials therein contained.

Broadly considered, 1 may use any suitable or desired form of mixing-receptacle suitable for this purpose, although I prefer a polyhedric or cubiform mixing-reccptacle,and particularly a cube box, which I believe will mix the ingredients more rapidly and thoroughly than a mixing-receptacle in which blades are employed for mixing. I do not, however, confine myself to a cubiform or p'olyhedric receptacle. As illustrated in the drawings, the yoke or bail 1) is pivoted to diagonally opposite corners of the cubiform mixing-receptacle and the sheave C is in a plane at right angles to an axis passing through said corners and midway of the latter.

If at any time it should be found desirable to temporarily use a bucket, the mixing-receptacle, with its bail, can be detached from the cable F, or the mixing-receptacle, with its bail, can be. detached from the head-block, which carries the pulleys F F.

It will also be observed that where the mixing-receptacle is to be moved from the point of charging to a point not sufficiently remote to cause the transportation of the mixing-receptacle in one direction to thoroughly mix the materials the carrier G can be caused to move forward and back along the track until the mixing-receptacle has performed the desired number of revolutions, it being an easy matter for an operator to determine the extent to which the carrier G should travel along the track in order to permit the mixing-receptacle to properly mix up a batch of concrete or the like, such as concrete, mortar, or the like.

hat I claim as my invention is- 1. In a system for mixing and delivering concrete and the like, a rotary mixing-receptacle journaled within a bail and having a sheave between the points at which itis journaled; guide-pulleys on the bail; an elevated carrier; and a raising and lowering cable passing about the sheave on the mixing-receptacle and passing over pulleys on the elevated carrier. 7

2. The combination with a carrying device comprising a carrier adapted for travel along an elevated track, and means for moving the carrier along the track, of a cubiform rotary mixing-receptacle provided with a ringsheave, and a raising and lowering cable connected with the carrier substantially set forth and passing about the sheave on the mixingreceptacle.

3. Means for mixing and delivering concrete and the like comprising a rotary cubebox mixing-receptacle provided with a door having a sheave ring arranged in a plane at right angles to its axis of rotation; an overhead cable; a carrier having pulleys over which said cable passes and from which said cable drops and loops the sheave on the mixing-receptacle; means for moving the carrier, and means for paying out said cable and in alternation therewith winding up the same to
